CLASS E POWER AMPLIFIER

摘要

Disclosed is a CMOS class E power amplifier. One embodiment of the present invention provides a class E power amplifier comprising: a main stage which comprises a first power amplifier implemented by a transistor; a driver stage which comprises a second power amplifier implemented by a transistor, and in which the output terminal of the driver stage is connected to the input terminal of the main stage and wherein an input signal is inputted to the second power amplifier; a first LC resonator which has one terminal connected to the output terminal of the driver stage and the other terminal connected to a ground and thus can be made AC circuit equivalent; and a second LC resonator which has one terminal connected to the input terminal of the main stage and the other terminal connected to a ground and thus can be made AC circuit equivalent.
